I was teaching a group of students who would ultimately become teachers, since at that time there were not many opportunities in Brazil for a highly trained person in science. These students had already had many courses, and this was to be their most advanced course in electricity and magnetism – Maxwell’s equations, and so on.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">The university was located in various office buildings throughout the city, and the course I taught met in a building which overlooked the bay.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I discovered a very strange phenomenon: I could ask a question, which the students would answer immediately. But the next time I would ask the question – the same subject, and the same question, as far as I could tell – they couldn’t answer it at all! For instance, one time I was talking about polarized light, and I gave them all some strips of polaroid.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Polaroid passes only light whose electric vector is in a certain direction, so I explained how you could tell which way the light is polarized from whether the polaroid is dark or light.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">We first took two strips of polaroid and rotated them until they let the most light through. From doing that we could tell that the two strips were now admitting light polarized in the same direction – what passed through one piece of polaroid could also pass through the other. But then I asked them how one could tell the&nbsp;<i style="margin: 0px; padding: 0px;">absolute</i>&nbsp;direction of polarization, for a&nbsp;<i style="margin: 0px; padding: 0px;">single</i>&nbsp;piece of polaroid.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">They hadn’t any idea.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I knew this took a certain amount of ingenuity, so I gave them a hint: “Look at the light reflected from the bay outside.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Nobody said anything.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I said, “Have you ever heard of Brewster’s Angle?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“Yes, sir! Brewster’s Angle is the angle at which light reflected from a medium with an index of refraction is completely polarized.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“And which way is the light polarized when it’s reflected?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“The light is polarized perpendicular to the plane of reflection, sir.” Even now, I have to think about it; they knew it cold! They even knew the tangent of the angle equals the index!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I said, “Well?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Still nothing. They had just told me that light reflected from a medium with an index, such as the bay outside, was polarized; they had even told me which&nbsp;<i style="margin: 0px; padding: 0px;">way</i>&nbsp;it was polarized.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I said, “Look at the bay outside, through the polaroid. Now turn the polaroid.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“Ooh, it’s polarized!” they said.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">After a lot of investigation, I finally figured out that the students had memorized everything, but they didn’t know what anything meant. When they heard “light that is reflected from a medium with an index,” they didn’t know that it meant a material&nbsp;<i style="margin: 0px; padding: 0px;">such as water</i>. They didn’t know that the “direction of the light” is the direction in which you&nbsp;<i style="margin: 0px; padding: 0px;">see</i>&nbsp;something when you’re looking at it, and so on. Everything was entirely memorized, yet nothing had been translated into meaningful words. So if I asked, “What is Brewster’s Angle?” I’m going into the computer with the right keywords. But if I say, “Look at the water,” nothing happens – they don’t have anything under “Look at the water”!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Later I attended a lecture at the engineering school. The lecture went like this, translated into English: “Two bodies… are considered equivalent… if equal torques… will produce… equal acceleration. Two bodies, are considered equivalent, if equal torques, will produce equal acceleration.” The students were all sitting there taking dictation, and when the professor repeated the sentence, they checked it to make sure they wrote it down all right. Then they wrote down the next sentence, and on and on. I was the only one who knew the professor was talking about objects with the same moment of inertia, and it was hard to figure out.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I didn’t see how they were going to learn anything from that. Here he was talking about moments of inertia, but there was no discussion about how hard it is to push a door open when you put heavy weights on the outside, compared to when you put them near the hinge –&nbsp;<i style="margin: 0px; padding: 0px;">nothing</i>!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">After the lecture, I talked to a student: “You take all those notes – what do you do with them?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“Oh, we study them,” he says. “We’ll have an exam.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“What will the exam be like?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“Very easy. I can tell you now one of the questions.” He looks at his notebook and says, ” ‘When are two bodies equivalent?’ And the answer is, ‘Two bodies are considered equivalent if equal torques will produce equal acceleration.’ ” So, you see, they could pass the examinations, and “learn” all this stuff, and not&nbsp;<i style="margin: 0px; padding: 0px;">know</i>&nbsp;anything at all, except what they had memorized.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I went to an entrance exam for students coming into the engineering school. It was an oral exam, and I was allowed to listen to it. One of the students was absolutely super: He answered everything nifty! The examiners asked him what diamagnetism was, and he answered it perfectly. Then they asked, “When light comes at an angle through a sheet of material with a certain thickness, and a certain index N, what happens to the light?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“It comes out parallel to itself, sir – displaced.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“And how much is it displaced?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“I don’t know, sir, but I can figure it out.” So he figured it out. He was very good. But I had, by this time, my suspicions.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">After the exam I went up to this bright young man, and explained to him that I was from the United States, and that I wanted to ask him some questions that would not affect the result of his examination in any way. The first question I ask is, “Can you give me some example of a diamagnetic substance?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“No.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I asked, “If this book was made of glass, and I was looking at something on the table through it, what would happen to the image if I tilted the glass?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“It would be deflected, sir, by twice the angle that you’ve turned the book.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I said, “You haven’t got it mixed up with a mirror, have you?”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“No, sir!”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">He had just told me in the examination that the light would be displaced, parallel to itself, and therefore the image would move over to one side, but would not be turned by any angle. He had even figured out how&nbsp;<i style="margin: 0px; padding: 0px;">much</i>&nbsp;it would be displaced, but he didn’t realize that a piece of glass is a material with an index, and that his calculation had applied to my question.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I taught a course at the engineering school on mathematical methods in physics, in which I tried to show how to solve problems by trial and error. It’s something that people don’t usually learn, so I began with some simple examples of arithmetic to illustrate the method. I was surprised that only about eight out of the eighty or so students turned in the first assignment. So I gave a strong lecture about having to actually&nbsp;<i style="margin: 0px; padding: 0px;">try</i>&nbsp;it, not just sit back and watch&nbsp;<i style="margin: 0px; padding: 0px;">me</i>&nbsp;do it.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">After the lecture some students came up to me in a little delegation, and told me that I didn’t understand the backgrounds that they have, that they can study without doing the problems, that they have already learned arithmetic, and that this stuff was beneath them.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">So I kept going with the class, and no matter how complicated or obviously advanced the work was becoming, they were never handing a damn thing in. Of course I realized what it was: They couldn’t&nbsp;<i style="margin: 0px; padding: 0px;">do</i>&nbsp;it!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">One other thing I could never get them to do was to ask questions. Finally, a student explained it to me: “If I ask you a question during the lecture, afterwards everybody will be telling me, ‘What are you wasting our time for in the class? We’re trying to&nbsp;<i style="margin: 0px; padding: 0px;">learn</i>&nbsp;something. And you’re stopping him by asking a question’.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">It was a kind of one-upmanship, where nobody knows what’s going on, and they’d put the other one down as if they&nbsp;<i style="margin: 0px; padding: 0px;">did</i>&nbsp;know. They all fake that they know, and if one student admits for a moment that something is confusing by asking a question, the others take a high-handed attitude, acting as if it’s not confusing at all, telling him that he’s wasting their time.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I explained how useful it was to work together, to discuss the questions, to talk it over, but they wouldn’t do that either, because they would be losing face if they had to ask someone else. It was pitiful! All the work they did, intelligent people, but they got themselves into this funny state of mind, this strange kind of self-propagating “education” which is meaningless, utterly meaningless!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">At the end of the academic year, the students asked me to give a talk about my experiences of teaching in Brazil. At the talk there would be not only students, but professors and government officials, so I made them promise that I could say whatever I wanted. They said, “Sure. Of course. It’s a free country.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">So I came in, carrying the elementary physics textbook that they used in the first year of college. They thought this book was especially good because it had different kinds of typeface – bold black for the most important things to remember, lighter for less important things, and so on.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Right away somebody said, “You’re not going to say anything bad about the textbook, are you? The man who wrote it is here, and everybody thinks it’s a good textbook.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“You promised I could say whatever I wanted.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">The lecture hall was full. I started out by defining science as an understanding of the behavior of nature. Then I asked, “What is a good reason for teaching science? Of course, no country can consider itself civilized unless… yak, yak, yak.” They were all sitting there nodding, because I know that’s the way they think.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I say, “That, of course, is absurd, because why should we feel we have to keep up with another country? We have to do it for a&nbsp;<i style="margin: 0px; padding: 0px;">good</i>reason, a&nbsp;<i style="margin: 0px; padding: 0px;">sensible</i>&nbsp;reason; not just because other countries do.” Then I talked about the utility of science, and its contribution to the improvement of the human condition, and all that – I really teased them a little bit.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I say, “The main purpose of my talk is to demonstrate to you that<i style="margin: 0px; padding: 0px;">no</i>&nbsp;science is being taught in Brazil!”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I can see them stir, thinking, “What? No science? This is absolutely crazy! We have all these classes.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">So I tell them that one of the first things to strike me when I came to Brazil was to see elementary school kids in bookstores, buying physics books. There are so many kids learning physics in Brazil, beginning much earlier than kids do in the United States, that it’s amazing you don’t find many physicists in Brazil – why is that? So many kids are working so hard, and nothing comes of it.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I gave the analogy of a Greek scholar who loves the Greek language, who knows that in his own country there aren’t many children studying Greek. But he comes to another country, where he is delighted to find everybody studying Greek – even the smaller kids in the elementary schools. He goes to the examination of a student who is coming to get his degree in Greek, and asks him, “What were Socrates’ ideas on the relationship between Truth and Beauty?” – and the student can’t answer. Then he asks the student, “What did Socrates say to Plato in the Third Symposium?” the student lights up and goes, “Brrrrrrrrr-up” – he tells you everything, word for word, that Socrates said, in beautiful Greek.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">But what Socrates was talking about in the Third Symposium was the relationship between Truth and Beauty!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">What this Greek scholar discovers is, the students in another country learn Greek by first learning to pronounce the letters, then the words, and then sentences and paragraphs. They can recite, word for word, what Socrates said, without realizing that those Greek words actually&nbsp;<i style="margin: 0px; padding: 0px;">mean</i>something. To the student they are all artificial sounds. Nobody has ever translated them into words the students can understand.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I said, “That’s how it looks to me, when I see you teaching the kids ‘science’ here in Brazil.” (Big blast, right?)</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then I held up the elementary physics textbook they were using. “There are no experimental results mentioned anywhere in this book, except in one place where there is a ball, rolling down an inclined plane, in which it says how far the ball got after one second, two seconds, three seconds, and so on. The numbers have ‘errors’ in them – that is, if you look at them, you think you’re looking at experimental results, because the numbers are a little above, or a little below, the theoretical values. The book even talks about having to correct the experimental errors – very fine. The trouble is, when you calculate the value of the acceleration constant from these values, you get the right answer. But a ball rolling down an inclined plane,&nbsp;<i style="margin: 0px; padding: 0px;">if it is actually done</i>, has an inertia to get it to turn, and will,&nbsp;<i style="margin: 0px; padding: 0px;">if you do the experiment</i>, produce five-sevenths of the right answer, because of the extra energy needed to go into the rotation of the ball. Therefore this single example of experimental ‘results’ is obtained from&nbsp;<i style="margin: 0px; padding: 0px;">a fake experiment</i>. Nobody had rolled such a ball, or they would never have gotten those results!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“I have discovered something else,” I continued. “By flipping the pages at random, and putting my finger in and reading the sentences on that page, I can show you what’s the matter – how it’s not science, but memorizing, in&nbsp;<i style="margin: 0px; padding: 0px;">every</i>&nbsp;circumstance. Therefore I am brave enough to flip through the pages now, in front of this audience, to put my finger in, to read, and to show you.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">So I did it.&nbsp;<i style="margin: 0px; padding: 0px;">Brrrrrrrup – I</i>&nbsp;stuck my finger in, and I started to read: “Triboluminescence. Triboluminescence is the light emitted when crystals are crushed…”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I said, “And there, have you got science? No! You have only told what a word means in terms of other words. You haven’t told anything about nature –&nbsp;<i style="margin: 0px; padding: 0px;">what</i>&nbsp;crystals produce light when you crush them,&nbsp;<i style="margin: 0px; padding: 0px;">why</i>&nbsp;they produce light. Did you see any student go home and&nbsp;<i style="margin: 0px; padding: 0px;">try</i>&nbsp;it? He can’t.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">“But if, instead, you were to write, ‘When you take a lump of sugar and crush it with a pair of pliers in the dark, you can see a bluish flash. Some other crystals do that too. Nobody knows why. The phenomenon is called “triboluminescence.” ’ Then someone will go home and try it. Then there’s an experience of nature.” I used that example to show them, but it didn’t make any difference where I would have put my finger in the book; it was like that everywhere.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Finally, I said that I couldn’t see how anyone could be educated by this self-propagating system in which people pass exams, and teach others to pass exams, but nobody knows anything. “However,” I said, “I must be wrong. There were two Students in my class who did very well, and one of the physicists I know was educated entirely in Brazil. Thus, it must be possible for some people to work their way through the system, bad as it is.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Well, after I gave the talk, the head of the science education department got up and said, “Mr. Feynman has told us some things that are very hard for us to hear, but it appears to be that he really loves science, and is sincere in his criticism. Therefore, I think we should listen to him. I came here knowing we have some sickness in our system of education; what I have learned is that we have a cancer!” – and he sat down.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">That gave other people the freedom to speak out, and there was a big excitement. Everybody was getting up and making suggestions. The students got some committee together to mimeograph the lectures in advance, and they got other committees organized to do this and that.</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Then something happened which was totally unexpected for me. One of the students got up and said, “I’m one of the two students whom Mr. Feynman referred to at the end of his talk. I was not educated in Brazil; I was educated in Germany, and I’ve just come to Brazil this year.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">The other student who had done well in class had a similar thing to say. And the professor I had mentioned got up and said, “I was educated here in Brazil during the war, when, fortunately, all of the professors had left the university, so I learned everything by reading alone. Therefore I was not really educated under the Brazilian system.”</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">I didn’t expect that. I knew the system was bad, but 100 percent – it was terrible!</div><div style="margin-top: 0.5em; padding: 0px; text-indent: 1.5em;">Since I had gone to Brazil under a program sponsored by the United States Government, I was asked by the State Department to write a report about my experiences in Brazil, so I wrote out the essentials of the speech I had just given. I found out later through the grapevine that the reaction of somebody in the State Department was, “That shows you how dangerous it is to send somebody to Brazil who is so naive. Foolish fellow; he can only cause trouble. He didn’t understand the problems.” Quite the contrary!
